JOHN A. THAYER, OF SOMERVILLE, MASSACHUSETTS.

CLAW-HAMMER AND SCREW -DRIVER.

SPECIFICATION forming part of Letters Patent No. 264,492, datedSeptember 19, 1882. Application filed September 1, 1881. (No model.)

To all whom it may concern Be it known that 1, JOHN A. THAYER, ofSomerville, in the county of Middlesex and State of Massachusetts, haveinvented a new and useful Improvement in the Combined Hammer andScrew-Driver; and I do hereby declare the same to be described in thefollowin g specification and represented in the accompanying drawings,of which- Figure 1 is a front view, and Fig. 2 a longitudinal andtransverse section, of a tool or implement containing my invention, thenature of which is defined in the claims hereinafter set forth. Fig.3 isan end view, and Fig. 4 a side view, of the jawed clamp; and Figs. 5 and6 are side views of the claw, to be hereinafter described.

The tool in some respects is like that for which Letters Patent, No.35,715, dated June 24, 1862, were granted to me; but the blade or shankof the said driver slides through the handle, and is directly attachedto and projects from the hammer-head. Instead of the A screwdriverhaving prongs or a claw at its terminus, the handle has such a clawfixed to it, or to a ferrule adapted thereto, there being in the shankof the claw a passage for the screw-driver to slide through.Furthermore, the handle has peculiar devices for clamping it to thescrew-driver, and there is to the claw of the handle a cap or cover, theconstruction and object of which will be hereinafter explained.

In the drawings, A denotes the hammerhead B, the screw driver, and O thehandle.

' The said screw-driver, fixed to and extended from the hammer-head,passes through the handle lengthwise thereof, and is adapted to slidetherein.

There is fitted or fastened on the upper end of the handle a jawedclamp, D, it having a screw-thread, a, on its outer surface. Such clampis tubular, except at its upper part, in which is a passage, 11, whosetransverse section is rectangular and corresponds to that of thescrew-driver.

Across this passage, near each end of it, is a saw kerf or slit, 0, thetwo slits causing the head or upper part, d, of the clamp toconstitutefour jaws, such head being conical or tapering on itsperiphery.

A tubular cap, E, formed as shown, encompasses and screws upon the clampD, the said cap havingtat its upper end a conical mouth or opening, a.Onthe cap being screwed down sufficiently, the jaws of the clamp will bythe said mouth, while descending upon them, be forced inward against thescrew-driver and will bind it not only on its two opposite sides, but onits two opposite edges.

The handle has fixed on its lowerend a claw, F, side views of which areshown in Figs. 5 and 6. The claw-shank has not only a screw, f, out uponit, but is formed with a rectangular passage, 9, for reception .of thescrew-driver, which is to freely slide through-the said shank.

A cylindrical cap, G, to cover the prongs of the claw, screws on theshank of the claw,

and has through its head a rectangular opening, h, for the passage ofthe screw-driver through such head. This cap G is to protect a personwhile using the implement from bein g accidentally injured by the claw.

In order to use the screw-driver the handle has first to he slid up tothe hammer head, after which such handle should be clamped to thescrew-driver. The hammer-head serves as a handle to the screw-driver,such head bein g grasped by the hand while the screw-driver may be inuse. .By having the screw -driver firmly fastened to the hammer-headinstead of being movable therein, as in my patented tool, all danger ofthe hammer-head slipping on the screw-driver is avoided. By having thescrew-driver to constitute a shank to the hammer-head and to be movableon the handle, and by having to such handle the means described forclamping it to the screw driver, the hammer-head may be adjusted todifferent distances from the handle, as occasion'may require.

What I claim as of my invention is as lows, viz:

1. The combination of the handle 0 and the perforated claw, F, fixedthereto, with the screw-driver and the hammer-head, and with thejawedclamp D and its screw-cap E.

2. The combination of the cap G, provided with the opening h,'asdescribed, with the handle and claw adapted and for use with the 7 JOHNADAMS THAYER.
